Be careful. Most watch "crystals" are not crystal at all but plastic today. "Crystal" does polish with cerium but not plastic. Plastic polish is also available from lapidary supply houses. A simple test if you are in doubt is to take a dress makers pin and along the edge if it is accesable drag the pin. If crystal it will slide and leave no mark. If plastic you will have a scratch. For polishing either, I use a power buffer and the speed is about 3000. A gentle touch and a spotless clean 6" to 8" wheel with your compound. Find an old beater to practice on first .

Gunsmith is right - I had a seiko divers watch with a saphhire crystal - you would need diamond to polish it.
